Hi,
my P760 is in a boot loop since yesterday. When it starts, the LG logo comes up and then it reboots again and again.
I tried the recovery option with the LG Tools, but after flashing the V20H-ROM, the bootloop is still there.
What can i do?
Thx
Mirko76
Today i tried fastboot and reflashed the bootloader:
Code:
sending 'x-loader' (384 KB)...
OKAY [ 0.200s]
writing 'x-loader'...
FAILED (remote: partition does not exist)
finished. total time: 0.210s
sending 'u-boot' (1024 KB)...
OKAY [ 0.530s]
writing 'u-boot'...
OKAY [ 0.210s]
finished. total time: 0.740s
Done
What does "partition does not exist" mean? is it dead?

After flash stock rom, did you try to hard reset your phone? http://www.hard-reset.com/lg-optimus-l9-p760-hard-reset.html
Yes, but without success.

There're many boot loop thread in L9 forum, please search for it. You can try this one first http://forum.xda-developers.com/showpost.php?p=40423549&postcount=2
I tried a lot of possibilities to repair the bootloop, but nothing helped.
I flashed the ICS Bootloader and flashed an ICS Rom with the offline method, but after Flash the boot Loop is still there.
A hard reset doesnt help.

Boot loop still there after flash kdz and hard reset! Strange. Flash kdz should restore factory rom and hard reset is remove all user data. What did you do before get that boot loop?
Did you try method in this thread http://forum.xda-developers.com/showthread.php?t=2411265
I did nothing before the bootloop. The battery was empty and after i plugged in the power supply, the phone was in the boot loop.

It usually means hardware(NAND) failure
i got that same partition does not exist error when i was trying to flash the wrong xloader and uboot in fastboot. not saying you're flashing the wrong ones, but that maybe it has something to do with fastboot.. ?

Could you have typed partition name incorrectly ? like "fastboot flash xloader..." instead of "fastboot flash x-loader..." ?

i'm fairly certain i did 'x-loader' because i was copying the text in a batch file you wrote. hard to remember exactly. when it happened, reading about possible problem with the phone i got sad inside. if i ever need fastboot again i'll try it through vmware ubuntu install
Im using a fastboot script, so i dont think that the filenames are wrong.
Ok, i give up. I think the phone is dead.

I've already tried this, http://forum.xda-developers.com/showthread.php?t=1088046&highlight=fastboot

That's the error I got..
Any solution for this?
Also, why am i breaking a rule for posting a question? There is no question section..
Had a problem where I was stuck on the htc logo loading screen. I assumed this was because I had been tinkering with mods and screwed up the whole rom, but after downloading a new version of android revolution hd and using the adb push command to put it on my internal storage, even after flashing it, i am still stuck on the htc loading screen.
if i can run the clockwork recovery mod or bootloader, but cannot get past the htc loading screen, does that mean the phone is broke?
also ive noticed the bootloader says unlocked "tampered" i dont know if thats significant, but i didn't notice it before.
i have googled this problem and the only reference i could find, was a few articles about the rom being corrupt and instructions how to flash a new one (which ive already done anyway)
i presume the phone is broke?

already did that and the other cache dvlaik or something. i think this is probably worse than a software problem.
Here is my issue, will try to explain as much as I can:
So I got the phone only booting to the LG logo and no further. So I read a couple threads which were mentioning about the LG Flash tool that I could try to use to restore the device, that did not work. So I tried to do Fastboot to see if that would help in any way. After trying, I was able to get Fastboot using @Lelus method ,now I cant get back the S/W upgrade mode, trying everything i could think of and still no progress. Would really love to fix this device and appreciate any help I can get.
days , I can help you. First download the drivers for your phone (if you have already remove them and re-load )
Next, download the LG Mobile Support Tool .
then go to your phone S / W upragade Mode (Press the volume up or down on the start)
then start the support tool as an administrator.
then press the Settings update recovery .
on the 90% of the phone restarts functional.
If you have any problem just say it to me!

Already tried all that. Phone does not boot or nothing. I can only access fastboot. I cant even flash the ICS u and x boot. When I try it says remote: partition doesn't exist.
Can you flash recovery through fastboot, and then acces it? I had similiar problem to yours, bricked my phone, barley made it to fastboot, i then flashed recovery using fastboot flash recovery recovery.img then booted to recovery and applied backup, or you might aswell flash a rom, if you don't have rom on your SD, use other phone to put ROM on sd, or card reader etc., the just install it. Just incase. i added recovery.img to my post.
Forgot to mention, after flashing recovery, try fastboot reboot recovery

Mismatched partition size(recovery) should not be a problem, it just saying that your recovery is smaller in size than the stock recovery. Did you got this problem after downgrading from lollipop? As a trial and error thing, try to flash stock recovery and see if it boots.

after flashing by "fastboot flash recovery recovery.img", boot into recovery directly by giving this cmd "fastboot boot recovery.img" this time it should overwrite your stock op recovery. try this and report back.
I'm assuming your trying to immediately boot into recovery after flashing because it will overwrite it. You can try the command "fastboot erase recovery" before flashing twrp. After flashing recovery completely turn off the phone. Then hold down volume down and proceed powering on into recovery. Sorry for the step by step if your not a noob just have to make sure we cover step by step. The above post is the proper way to boot after flashing try it first.
